Definition

Hazardous Air Pollutants (HAPs), also known as air toxics or hazardous air emissions, are a group of airborne substances identified as potentially harmful to human health and the environment. These pollutants encompass a wide range of chemicals and compounds, including volatile organic compounds (VOCs), heavy metals, and other toxic substances. HAPs are typically associated with industrial processes, vehicle emissions, and other sources of pollution. Due to their potential health risks, they are subject to regulation and monitoring to mitigate their impact on air quality and human well-being.
